# mapmaker v1.1
# reads a file with lines of format:
#   nnnn A000000-0 NSG
# or
#   Jd aaaa bbbb cccc xxxx
# or
#   RZ nnnn
#   AZ nnnn
# where nnnn is a hex map coordinate (0101 through 0810), A000000-0 is a UPP,
# NSG indicates Naval Scout or Gas Giant (omit or replace with . if none)
# and d is a single digit followed by a list of hex coordinates.
#
# It then draws a TAS form 6 with systems plotted and decorated with
# X-boat paths drawn.
